I have a bit of a nonstandard sbt build setup due to the need to use both Eclipse and sbt.
My sources are in src/main/scala and src/com/companyname/[folder1, folder2, etc] directories.
How can I set up sbt so it also generates documentation for these additional folderX folders under src/com/companyname?
tl;dr Use the following in build.sbt:
unmanagedSourceDirectories in Compile += sourceDirectory.value
inspect is your friend.

Under Dependencies you'll find that doc task depends on compile:doc::sources among other things. Use inspect again with the setting.

Under Dependencies you find that it depends on compile:sources and following along you find that you should change unmanagedSourceDirectories setting to have what you want.
